Have tried a bunch of different DC to DC converters and this is the only one that even comes close to delivering rated specs. Fairly easy setup, and can be configured to enable output automatically at powerup. I'm using it to charge a LiFe battery from my main car battery on a switched source. My input voltage can drop as low as 10V under load (due to a long wire run) and I've got the output set to 14.4V and the battery pulls it down to mid 13's when it's charging. This board will deliver about 12A pretty reliably so about 160W.Some of the other DC to DC boost converters I've tried either won't power on at all, or switch off when the input voltage drops, or just won't give me more than 8-10A (while often being rated for 15-20A). This one just works.The only issue I have is that it has no case, and all the electronics are really out there on both sides of the board, so be careful you don't short it out on something.

Liked it so much I bought two. I use these with laptop chargers to make E bike/scooter chargers. They work great and are much more reliable, adjustable and better quality then oe ones.

When shopping for a 120VDC voltage booster, I considered another product. Amazon had noted that it was returned very frequently, so to be careful with the order. In the comments, someone noted that it had a positive ground common to both input and output. This would be a no-go for my application, and probably for most applications. So I kept looking.The listing for THIS booster circuit didn't specify positive or negative ground, but the manual seemed to imply a negative ground. Indeed it is a negative ground, common to both input and output. (It can be wired with three wires if desired.)The board was easy to install, and it operates rather intuitively. It can be programmed to put out a predetermined voltage when powered up (without requiring any buttons be pressed). Or it can be programmed to produce that voltage only when a button is pressed. When it is not producing the programmed voltage, it puts out a fraction of a volt less than the input voltage. (I didn't test whether this voltage could be killed with a small resistive load.)I powered my board with 12VDC and boosted to 120VDC. When powering up, it takes a few seconds for the capacitors to charge and for the output to ramp up to 120VDC. The output is steady and smooth, and the voltage is accurate.I can't attest to how well the board performs under a heavier load. I'm only drawing about 25 mA from the board! Others have suggested that the board whines under load, However, with my light current draw, I have heard no whining.

This is the second one that has failed. I haven't finished repairing the first one but the second one failed because the fan stopped working. For some reason the voltage to the fan dropped low enough that it overheated the fan and the fan failed. Then the main for mosfet blew up. I replaced the Mosfet and discovered that fan no longer worked. I connected a new fan and voltage to the fan should be 12v but it was only 2.3v and the fan would not spin. The temp of the heat sink was over 200 deg F. so the fan should have been spinning really fast. I connected a separate 12v wall wart to the fan and started charging my 52v ebike battery. At 30 minutes I can hold my fingers on the heat sink for about 3 seconds before it gets uncomfortably hot. I have a 3 year old bst-900w and it still works fine. I have never had to repair that one. I am really happy to get my hands on a charger that is capable of MPPT and 120v for this price. The problems I have had don't bother me as long as I can repair it. I wish they made more info available for repairing this boost converter.
